Function 𝐹_SF(𝑟,𝛼,𝜆) for 𝜆=5 Mpc/ℎ and several values of parameter 𝛼. 𝛼=0, That is, the standard Newtonian case is the horizontal line. The long dashed line above the horizontal standard line is for 𝛼=1. The dotted line is for 𝛼=1/2, and the dotted-dashed line is for 𝛼=1/4. For negative values of 𝛼 the lines are below the standard horizontal case. Small dashed line is for 𝛼=−1/2 and the double-dotted-dashed line is for 𝛼=−1/4.
